Slice the eggs in half lengthwise. Remove yolks and place into a bowl. Cover and place in the fridge.
Fill four bowls with ¾ cup cold water each. Add food coloring using the following ratios: 4 red drops for pink, 4 drops blue for light blue, 4 drops green for light green, and 3 drops red & 3 drops red for purple.
Place 6 egg halves into each bowl. Allow the eggs to soak for one hour, or until eggs are desired color.
Remove eggs from bowls and gently dry and place on a paper-towel lined plate.
Remove eggs yolks from fridge and add remaining ingredients. Beat yolks with a hand mixer so they become light and fluffy. Transfer egg yolks to a plastic resealable bag, and push mixture into the tip. Cut the tip and gently pipe the egg yolk mixture into the egg halves.
Transfer eggs to serving tray, and enjoy.
